Abstract

The invention relates to novel metamaterials which are polymer composites containing from 0.5 wt% to 45 wt% of copper flakes and /or nanoflakes in polymer matrix as compared to polymer matrix. The invention pertains also to the method for obtaing novel metamaterials which consists in : a) obtaining copper foil or nanofoil in the process of acid copper salt solution electrolysis using pulse current, b) removing the copper foil from metallic base, c) mixing it with polymer and d) composite molding. Polymer composites obtained by the method according to the invention exhibit the properties characteristic of metamaterials which means that they show diamagnetic (smaller than unity) effective magnetic permeability and very large (in-plane) effective permittivity.
